The reference character 39 denotes amortar-'pump communicating with a source of supply (not shown) said pump operative] b eing connected as at 40 to the counter-shafiiI 36. Communicating with theoutlet of the pump 41 is a vertically disposed mortar supply pipe -42 opening at its upper end into a mortar collector 43, having a reduced lower portion 44 with which communicates a flexible mortar feed pipe 45 having .extending therethrough van endless chain;y 46 for the A purpose of conveying the mortar through said feed pipe 45 to the mortar distributing deviceto be presently referred to. The pipe 45 opens into the mortar distributor vas olearl opera .ed in. any suitable manner.

'Projecting forwardly-from the bar 11 is a stub -ehaft,47 provided 'with a pinion' 46.L Which'mesls With and is driven by the gear Wheel 2l. Journaled in and projecting f0rwardly from the bar 11 is a shaft 48 carrying a gear 49 whichme-shes with and' is 'driven by the pinion 46.. Mounted upon the shown in Fig. 10. The chain 46 is outer end' of the shaft 48 is a sprocketv Wheell 50 for a purpose to be'presently referred to.

Secured to the offset portion 10 and to tlie strap 8 are the upper and lower inner longi tudinal side bars 51, 52, of a carriage supporting frame. The lower bars 52 are also secured to and are'of' greater'length than .the base 1. The upper and lower outer sidebars of the carriage supportingrame are indicated at 53, 53a. The bars of the frame .are angle shape in cross section. The ends of thevcarriage supporting frame are indi- "cated at 54, are rectangular in cross section andare secured to the ends of the side bars 51, 52 and A53.. Each end or' the carriage supporting -frarne is provided with a bear,

ing; these bearings are indicated at 55, 56.- Projecting inwardly from and carried by the bearing' 55 is a shaft? provided With a grooved pulley 58. Adjustably mounted in andproject-ing inwardly from the bearing 56is a shaft .59 provided-'With a grooved ,Y

pulley GO. The shaft '59 is arranged below the shaft 57. Traveling over the pulleys 58 -and 60 is an endless chain 61v which is driven by the sprocket Wheel 50. The chain 61 also travels over the idlers G2 and (i3 and engages and-rotates a sprocket pinion 64 fixed upon the shaft 65a' of the operating cylinder' 65 whichv constitutes the brick carrier thereby revolving the latter.

-Mounted Within the. carriage supporting .i

frame is a' traveling carriage 71. for supporting and shifting the cylinder 65.A The car riage comprises a pair of upright-S66, 67,

each having -a pair of depending supports G8', each'oi. which carries a. pair of rollers 69 arrangedin alinement but spaced from each other. The upperrollers 69 of the pairs of rollers travel upon the upper faces of the horizontal portions of the bars 52, 53, while the lower rollers 59 of' the pairs of rollers travel against the lower faces; of the horizontal portions of the bars 52, 58. "The horizontal portions of the bars'52, l53 con-, sti'tute a track for the carriage of the operating'lcylinder 65, The uprights 66,. 67v` are connected by the tie bars 70.

The carriage 71 is shifted by the gear Wheel 23 which engages with a longitudinally extending track 72 that is supported` by arms 7.2* extending outwardly from the upright 66 and below the offset 10. iVhen the clutch sleeve 25 couples the gear 23 to v the shaft 18, the carriage 71 is moved longitudinally of its supporting trame. The movement of the carriage 71 is an intermittent one due to the action of the cam 20 and sprin 33 alternately shifting the bell crank to a ternately move the clutch sleeve 25 in oppositedirections.v In this connection it will be stated that during one po ion of the revolution of the shaft 18 the ar 23' is coupledto the shaft 18 and durilg another porton of the revolution of the shaft.

Inr this position of the stop arms, the carriage is held against shifting on its track While the cylinder or brickcarrier is rotating and the brick is being laid. The stop arms are swung to one side of the path of travel of the guide wheels 69 simultaneously with the shitting of the clutch to 'step the carriage forward so as to lie in the position shown by dotted lines in Fig. fi, by means of a litt 107b (see Fig. 8) which is mounted for vertical movement in keepers 107, 1071-'carried'by the bearing 56. The. toot 107e on the lower end of this lift turns the bar 107 as the liftis raised. For raising on the inner tace of the Wheel for engagement with the vout-ivardly-eXtending upper- .end 107g on the lift. A spring 107h has one end connected to the keeper 107 and its other end to a pin 107,carried by the litt to eiect quick'return of the lift and permit spring 107il to .return bar 107. The lug or outwardly-extending end 107g moves in a slot 107k provided therefor and is supported -in its normal position by a pin 107I resting on keeper 107c While'its upward movement is limited by the pin 107i.

The operation of the' apparatus is as follows: A layer of mortar having been placed upon the periphery of the cylinder "1n tront of the pocket 73 by means ot' the distributing device` a. brick 81 is place" between the plate 75 and one side wall ot the pocket 71, either by hand or by means ot asuitable conveying apparatus, this being quickly and easily performed during the rotation and `the forward movement of the" cylinder 65. Upon further rotation of the cylinder 65, a portion of the layer of mortar placed thereon is first caused yto slide by means of the Scraper 95 into the interior of the cylinder 65 through the flap 88, which is open during the movement, ivhereupon the flap 83 is again closed by means of the cam groove 85 and thc armS/t, and the scraper 95 commences to slide the remainder of the layer lof mortar against one side of the brick. 81;.(Fig. 6). Upon further motion ot' the cylinder 65 the layer of mortar in front of the-'scraper 95 is pressed against one side of thebrick 81, whereupon `the scraper is forced aside by means of the striker 97, so as Ito free the path for the brick 81 (Fig. 7). Upon further rotation of the cylinder 65, the brick 81 reaches a downward position andis liberated in this position by the plate 475 being drawn back by the hook 77 and retractor 78, so thatl it falls next to the last laid portion of the course, upon. a layer of mortaralready laid down (Fig. 8). Upon jgbggyrotation -of the cylinder 65, thei springs 94 come in contact with the brick .81 just laid and press the latter down to its corv rect level and against the bricksy previously laid (Fig. 9). The mortar squeezed out thereby may, if desired, beV caught .by a special scraping device (not illustrated). At this moment. fresh mortar is supplied to the cylinder 65 by means of the distributing device, the drum 100 being set in rotation by the driving gear, and a certain quantity of mortar being discharged from the voutlet 101v by means of the knives 102. The stream of mortar is cutoft by means of a fixed Wire 110. This stream of mortar passing out of the distributing device reaches the cylinder 65 in such a manner that a part of the stream 'falls in 'the direction of motion, againstI the flap .83 and partly behind the latter. When this movement oit the cylinder 65 takes placen the. rods 108 ot the stopping device are maintained in their lowered position, so that they stop the guide wheels of the carriage 71. At the same time that part of the cam 20 having the larger diameter comes in contactvvith the bell-crank lever, so that the Wheel 21 is coupled with the shaft 18 and sets the chain 61 in motion through the medium of the sprocket wheel, 50, the motion being transmitted to the shaft 65a of the cylinder 65 by means of the sprocket pinion 64. After the springs 94 have come in contact with the freshly laid bricks, that part of the disk 20 having the smaller diameter comes in contfct with the bell-crank lever, so that the Wheel 21 is dis# engaged and the wheel 23 is coupled with the shaft 18. By means of the stopping device, the stop arms 108 are at the same time removedfrom the path of the guide wheels of the carriage, so that by the act-ion o the wheel 28 on the rack 72 the -carriage is now advanced through a distance equal to the exact spacing of the bricks, owing to the stopping device immediately falling back.

As soon as this advance is completed, that part of the disk 2O having the larger diameter again comes in Contact With the bellcrank lever, so that the `Wheel 21 again engages with the shaft 18 `tor the purpose of rotating the cylinder 65 and performing another bricklayingoperation. During the advance of the carriage, the pinion 88 .of y

the small cylinder 86 mounted inside the cylinder 65, engages with the rack 89, turns the cylinder 65 and causes the knives 92 projecting out of the cylinder 86 to discharge a determined quantity of mortar from the aperture 92a. Corresponding to the advance of the carriage, thev stream of mortar, which is cut oit' by means of' wire 112 stretched across the trolley frame underneath the cylinder 86 is laid down next to the last laid bric-k and upon the course of bricks below. The clutch is now again changed over. as

before described, and roation oi the casi `ridgethereupon again talics place for the kpurpose of laying a fresia brick.
